Advanced Brush Tyre Modelling

Advanced Brush Tyre Modelling

This book provides an in-depth understanding of tyre dynamics. In the first three chapters, new concepts are introduced in respect to the classic theory. Analytical results are derived step-by-step to guide the reader through the governing equations of the model. Transient phenomena are explained in a relatively simple way according to the brush theory. The analysis is extended to cover the case of large camber angles, which is often disregarded. The principal mechanisms behind the transient generation of tyre forces and moment are discussed in general terms, and exact solutions to the rolling contact problem are given for simple contact geometries. The last part of the book is dedicated to the approximated theories of transient generation of tyre forces and moment. Two different models, suitable for use in vehicle dynamics applications, are presented and compared.

This open access book constitutes the thoroughly refereed proceedings of the First International ISCIS Security Workshop 2018, Euro-CYBERSEC 2018, held in London, UK, in February 2018. The 12 full papers presented together with an overview paper were carefully reviewed and selected from 31 submissions. Security of distributed interconnected systems, software systems, and the Internet of Things has become a crucial aspect of the performance of computer systems. The papers deal with these issues, with a specific focus on societally critical systems such as health informatics systems, the Internet of Things, energy systems, digital cities, digital economy, mobile networks, and the underlying physical and network infrastructures.

Modeling and Applied Mathematics Modeling the behavior of real physical systems by suitable evolution equa­ tions is a relevant, maybe the fundamental, aspect of the interactions be­ tween mathematics and applied sciences. Modeling is, however, only the first step toward the mathematical description and simulation of systems belonging to real world. Indeed, once the evolution equation is proposed, one has to deal with mathematical problems and develop suitable simula­ tions to provide the description of the real system according to the model. Within this framework, one has an evolution equation and the re­ lated mathematical problems obtained by adding all necessary conditions for their solution. Then, a qualitative analysis should be developed: this means proof of existence of solutions and analysis of their qualitative be­ havior. Asymptotic analysis may include a detailed description of stability properties. Quantitative analysis, based upon the application ofsuitable methods and algorithms for the solution of problems, ends up with the simulation that is the representation of the dependent variable versus the independent one. The information obtained by the model has to be compared with those deriving from the experimental observation of the real system. This comparison may finally lead to the validation of the model followed by its application and, maybe, further generalization.

Governance and Performance of Water Utility Firms

Governance and Performance of Water Utility Firms

In Italy, the debate about the reform process, that has involved the water sector for several years, cannot be considered concluded. It seems exclusively ideological and often it does not consider the business administration perspective, which certainly could make a contribution to the solution of different problems. Politicians and researchers, for example, show very little interest for the economic and financial performance of water utility firms, focusing almost exclusively on the different ways for providing the services or on the ownership structure. This work analyzes the variables characterizing the outsourcing process in the water sector. It also explores the connection of such variables with the performance of companies and local government authorities involved in the delivery process. Subsequently, the work explains the results of an exploratory analysis of different cases in the international context, making also a comparison about the performance. Lastly, the work verifies the existence of some best practices and evaluates the adaptability of these best practices in the Italian context.

L’urgenza vascolare è la vera urgenza. Data la variabilità delle presentazioni cliniche, il radiologo è sempre più spesso chiamato in causa per problemi diagnosticodifferenziali e a lui sono demandati l’inquadramento nosologico e le scelte terapeutiche dei casi dubbi. Se il tempo è l’unica variabile determinante, la diagnosi deve essere tempestiva ed accurata perché si possano attuare le scelte terapeutiche idonee. Pertanto è necessario che il radiologo sappia agire con sollecitudine e “precisione chirurgica”. Lo scopo del volume è fornire, attraverso la presentazione di un’ampia casistica, un mezzo facile, veloce e stimolante, attraverso cui il lettore possa confrontarsi.
